Problems with Radeon 9550 driver installation

I just got a Radeon 9550 graphics card, and I've been having problems trying to install the thing. When I try to install it from the CD, a message pops up saying:

Severe
Setup was unable to complete installation.
Try to setup your display adapter with a standard VGA driver before running setup

When I try installing it with Windows New Hardware Wizard, I get the message:

An error occured during the installatioin of this device
- The data is invalid

I really need help, what should I do? :confused:

This is the data invalid solution - Data invalid solution (http://www.xtra.co.nz/help/0,,6156-1359658,00.html)
For modem read video/graphics/display That might be allow you to install.

You might have toboot into VGA mode(tap F8 AT Startup,select VGA mode) and then try installing.

Further possibilities if that didn`t work -Make sure your system is free of any remnants of previous video card drivers
use this - Driver cleaner (http://www.majorgeeks.com/download3214.html ) If necessary.

If you get problems look here - Helpful link (http://www.techspot.com/vb/all/windows/t-7229-How-do-I-Enable-VGA-mode.html) and Helpful link (http://www.pcbuyerbeware.co.uk/VideoProblems.htm) and Helpful link (http://www.winfx247.com/247reference/msgs/0/1527.aspx)

Don`t say you haven`t got enough information :)

Thank you very much, it worked! After I sorted out the "Data invalid" problem, I was able to install everything else. Again, thanks! :)

I would like to know which of those instructions worked for you, i tried all of them and none worked.

tried the driver removal tool still nothing

I could not make any sence of the link to the modem page.
